DOOR-FASTENER.

SPECIFICATION forming part of Letters Patent No. 610,624, datedSeptember 13, 1898.

Application filed June 7, 1897. $erial No. 639,657. (No model.)

To all whom it may concern.-

Be'it known that I, LESLIE J. GAMBLE, a citizen of the United States,residing at ,Moline, in the county of Rock Island, in the State ofIllinois, have invented certain new and useful Improvements inDoor-Fasteners, of which the following is a specification.

My invention relates to fasteners adapted to exert pressure upon theclosed door, and is especially adapted to refrigerator-doors and otherdoors which it may be desired to hold firmly in place. Its object is toprovide an improved construction whereby a more convenient and efficientfastener is provided.

In the drawings accompanying and forming a part of this specification,wherein the same character of reference refers to the same part'in theseveral views, Figure 1 is a plan of my fastener. Fig. 2 is a sideelevation of the same. Fig. 3 is a verticalcross-section of the same.Fig. 4 is a vertical cross-section of the upper plate. Fig. 5 is a planof the lower plate. Fig. 6 is a cross-section of the same. Fig. 7 is aview of the connectingrivet.

In the drawings, D is the catoh or strikingplate, made relatively heavyand strong and adapted to be firmly secured to the wall and to engagethe upper plate of the fastener proper.

B is the lower plate, in the shape of a disk with a segment cut off, asshown in Fig. 5. This plate is adapted to be attached to the door withthe straight edge flush with the edge of the door. The curved edge ofthe plate B is raised for about the thickness of the plate, leaving acorresponding depression beneath as a path for the lip F, hereinafterdescribed. A flange 0 projects downward from the straight edge of thelower plate and serves as a stop for the lip F at the upper end of thestraight edge. The central portion L of the plate B is raised, leaving acircular depression beneath, and the raised portion bears on itscircumference a circular flange K.

The upper plate A is adapted to be concentrically superimposed and toturn upon the lower plate. It is a disk having an irregular segment cutaway corresponding to the similar segment of the lower plate, but cutinward more deeply, as shown in Fig. 1.

It bears a radially-projecting handle a, made integral with the plate onwhat may be termed the upper limb of the plate, and a camiiange aextending around the outer edge of the upper plate, adapted to engagethe catch D, and rising toward the handle.

F is a lug borne on the upper limb at the circumference of the plate A,extending downward for a distance equal to the thickness of the lowerplate and bearing an inwardly-projecting lip F, adapted to follow thepath or groove beneath the raised edge B of the lower plate. The centralportion of the upper plate A is raised at A, leaving the cylindricalspaces II I beneath.

G is a coil-spring interposed between the plates, occupying the space H.

. The rivet E passes through the centers of the upper and lower platesand, engaging the Washer M, holds the plates together, allowing theupper plate to revolve on the lower, while the push of the coil-springproduces friction enough to hold the upper plate in any position inwhich it may be placed.

When the upper plate is turned so as to bring its opening opposite thecatch D on the wall, the door will close, the handle a then occupyingsubstantially a vertical position. The door being closed, the handle maybe turned from left to right, causing the plate A to turn, bringing thecam-flange into engagement with the catch D. It is obvious that the doorcan be pressed as tightly into place as may be desired and will be heldthere by the cam. The pressure thus brought upon the cam-flange at thecircumference of the disk would unduly strain the rivet at the centerand in practice would cause it to bend or break, except that the lip Fengaging the opposite edge of the lower plate furnishes the necessarysupport and prevents undue strain on the rivet.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is V 1. A fastener of the character describedcomprising a hook-shaped catch adapted to be affixed to one of the partsto be locked together, a base-plate adapted to be affixed to the otherof the parts to be locked together and having a straight edge tocorrespond with the edge of the same and flanged to take over thelatter, said base-plate having a curved back edge raised to form amarginal depression, and a cam-plate pivoted to the baseplate having acurved marginal cam-flange to engage the hook-shaped catch and having alug with a lip projecting into the marginal depression of the base-platewhich forms a path for said lip, rotation of the cam-plate being limitedby abutment of said lip against the flange oh the straight edge of thebaseplate.

2. A fastener of the character described comprising a hook-shaped catchadapted to be affixed to one of the parts to be locked together, abase-plate adapted to be aiflxed to the other of the parts to be lockedtogether and having a straight edge to correspond with the edge of thesame and flanged to take over the latter, said base-plate having acurved back edge raised to form a marginal depression, a cam-platearranged over said baseplate having a marginal cam-flange to engage thehook-shaped catch and being recessed at the middle in the side next tothe base-plate, said cam-plate having a lug with a lip projecting intothe marginal depression of the base-plate, which forms a path for saidlip, and rotation of the cam-plate being limited by abutment of said lipagainst the flange on the straight edge of the base-plate, a pivot-pinconnecting the two plates and passing through the recess in thecam-plate, and a spiral spring occupying said recess and surroundingsaid pivot-pin and bearing against the cam-plate and base-plate, wherebyit exerts itself to press the cam-flange into close engagement with thehook-shaped catch, substantially as described.

3. A fastener of the character described comprising a hook-shaped catchadapted to be aflixed to one of the parts to be locked together, abase-plate adapted to be aliixed to the other of the parts to be lockedtogether and having a straight edge to correspond with the edge of thesame and flanged to take over the latter, said base-plate having acurved back edge raised to form a marginal depression, and a cam-platepivoted to the baseplate having a curved marginal cam-flange to engagethe hook-shaped catch and having a lug with a lip projecting into themarginal depression of the base-plate which forms a path for said lip,rotation of the cam-plate being limited by abutment of said lip againstthe flange on the straight edge of the baseplate, and the cam-platebeing cut away to terminate the low end of the cam-flange and permitcomplete disengagement of the catch and cam-plate by turning of thelatter.

4. A fastener of the character described comprising a hook-shaped catchadapted to be affixed to one of the parts to be locked together, abase-plate adapted to be affixed to the other of the parts to be lockedtogether and having a straight edge to correspond with the edge of thesame and flanged to take over the latter, said base-plate having acurved back edge raised to form a marginal depres sion, a cam-platearranged over said baseplate having a marginal cam-flange to engage thehook-shaped catch and being recessed at the middle in the side next tothe base-plate, said cam-plate having a lug with a lip projecting intothe marginal depression of the base-plate, which forms a path for saidlip, and rotation of the cam-plate being limited by abutment of said lipagainst the flange on the straight edge of the base-plate and thecam-plate being cut away to terminate the low end of the cam-flange andpermit complete disengagement of the catch and camplate by turning ofthe latter, a pivot-pin connecting the two plates and passing throughthe recess in the cam-plate, and a spiral spring occupying said recessand surrounding said pivot-pin and bearing against the cam-plate andbase-plate, whereby it exerts itself to press the cam-flange into closeengagement with the hook-shaped catch, substantially as described.
